So, today I finished my PSP Graphics Engine. It's a very simple thing coded for a 'last minute' PSP project. It's not terribly full featured (yet, it's only 2 weeks old), but I've written a dozen engines (graphics or otherwise) for nearly every modern platform under the sun, and this engine will grow as needed.

So why the hell am I posting here?

Well, I see all sorts of odd questions about graphics, image formats, CLUT, etc... and I want to help. But for various reasons, I really can't say much about API usage details, techincal info, etc... BUT I _can_ talk about general graphics 'how to' stuff. I _can_ tell you what I did, without too much detail, and I can take questions when possible.

So... I need a few days to really gather my thoughts & write this up. But I want to know a few things before I am done:

First, what sorts of graphics topics do you want me to cover besides the ones I am already planning to address (graphics processing & general logic overlap, 'zero stall' display lists (aka fire & forget), proper image loading & formating techniques, limited resource management (VRAM is a great example on the PSP), etc) ?

Next, in the areas I am going to cover, are there any projects out there that render _only_ from textures in VRAM? Are there any that render entirely offline (the render isn't occuring as the list is built, but the list isn't static or pre-compiled), etc, etc, etc?

I have looked around and I haven't seen _any_ terribly advanced topics covered around here, and while I don't want to get myself into trouble, I do feel like better techniques need to be talked about in this forum & put to use.

So, please, tell me what you think, and if I see enough attention, I'll throw up some _very_ handy info, albiet without too much raw C code (but I will use pseudo code, I am sure that's alright).

You mean you're an "official" dev? Please do! Unless you're under NDA or something... I guess you can judge how much you're allowed to say.

Good idea !

I really would like to know more about graphic implementation stuffs and this article looks really interesting !
